Greenland earthquake and tsunami – hazards of melting ice?
Following the news over the weekend with a trip to Greenland this summer at the back of my mind, my attention was immediately caught by reports of a tsunami and earthquake in Greenland. Four people were reported missing. Buildings had been swept away, including the power station on the island of Nuugaatsiaq. Greenland is not the first place that comes to mind in connection with earthquakes and tsunamis. But in fact they are not as rare as you might think.
The cause of the weekend’s event is still unclear. But a tweet from the Greenland Climate Research Centre links to an article in the Washington Post from June 25 2015:
The article reports on a paper published in the journal Science at that time by researchers from Swansea University in the UK, the Lamont-Doherty Earth Observatory at Columbia University and several other institutions. It says the loss of Greenland’s ice can generate “glacial earthquakes”.
“When vast icebergs break off at the end of tidal glaciers, they tumble in the water and jam the glaciers themselves backwards. The result is a seismic event detectable across the Earth”.
Worrying reading indeed, as GCRC wrote in their tweet.
The Washington Post article quoted Meredith Nettles from Columbia, one of the co-authors.
She specifically mentions the tsunami effect:
“The tsunami is caused because the iceberg has to move a lot of water out of the way as it tips over”.
Too early to say
I have been trying to find more information on what the experts think caused this weekend’s particular event. So far, there is no clarity. But the GCRC tweet with link to the Washington Post article seems to indicate they think it could be ice-related.
Another theory is that the quake and tsunami were caused by a landslide. The news agency DPA says the Geological Survey of Denmark and Greenland are still trying to determine the cause of the tsunami.
“Initially, geologists believed it was triggered by an earthquake, but another theory blamed a large landslide from one of the mountains on the fjord system”.
It seems the Danish Arctic Commando published images showing signs of an extensive landslide.
“Tsunamis and large waves at times affect Greenland’s coasts, but, according to the Geological Survey, they are usually caused by landslides and the breaking off of ice from melting glaciers”, the agency writes.
DPA earlier noted that the Danish earthquake authority GEUS had recorded a 4.0 quake.
Warning from Greenland ice cores
One way or other, the weekend tsunami is unlikely to allay anxiety about the effects of rapidly melting substantial quantities of ice.
And a study just published by Germany’s Alfred-Wegener-Institute (AWI) provides more food for thought about human-induced changes to our climate. It indicates that the gradual nature of the changes we are making to the CO2 concentration in the atmosphere is no guarantee that the resulting climate change will also be gradual. On the contrary. Computer models based on information from ice cores from Greenland show that in high latitudes of the northern hemisphere, there were abrupt changes in climate, which the scientists attribute to a gradual increase in CO2.
During the last ice age, they say that the influence of atmospheric CO2 on the North Atlantic Current within a few decades led to an increase in temperature of up to 10 degrees Celsius in Greenland. The study, published in the journal Nature Geoscience, by scientists from AWI and the University of Cardiff shows that in recent earth history, there have been situations when gradual increases in CO2 concentrations at what are known as “tipping points” led to abrupt changes in ocean circulation and climate.
Sudden warm age on the horizon?
Lead author Xu Zhang says the study is the first to prove that a gradual increase in CO2 can set off very rapid warming, based on interactions between ocean currents and the atmosphere.
The authors also show that the rise in CO2 is the main cause of chances in ocean currents during the transition from an ice age to a warm period.
Of course, they add, the framework conditions today are different from those during an ice age, so it is not possible to say the rise in CO2 will have similar effects in future.
But they say they can definitely show that there were abrupt climate changes in Earth’s history, which can be traced back to continual rises in CO2 concentrations.
Reason enough for concern to people living on the coast of Greenland – not to mention the rest of us, given the key role the world’s biggest island, with the biggest freshwater mass in the northern hemisphere sitting on top of it in the form a giant ice sheet, plays in influencing climate and sea levels around the globe?

Working for an international broadcaster which has Africa as one of its key target groups, I often find it difficult to interest some of my colleagues in what is happening in the Arctic. So my attention was caught instantly when I came across an article by Chelsea Harvey in the Washington Post: A climate chain reaction: Major Greenland melting could devastate crops in Africa.

Cheap oil from the Arctic? Fake news, says climate economist Kemfert
This week I came across an interesting publication about to come on to the German market.
“The fossil empire strikes back” (Das fossile Imperium schlägt zurück) is the translation of the catchy title of a new book in German by Professor Claudia Kemfert, head of the department of energy, transportation and environment at the German Institute for Economic Research in Berlin (DIW Berlin,) and professor of energy and sustainability at the Hertie School of Governance, in Berlin.
She has also acted as advisor to the German government, the European Commission and is on the steering committee of the renowned Club of Rome.
A fossil fuels revival: happening now, or alternative facts?
I called her up to record an interview for our Living Planet radio show to find out what was behind the headline, and the sub-title: “why we have to defend the “Energiewende” (energy transition) now.
Prof Kemfert believes the fossil fuels sector is really working hard at making a comeback. That, she says, is not fake news, but the fossils lobby makes use of the latter in its attempt to turn the clock back in terms of energy production.
While the global transition towards renewable energy has been successful in recent years, with the costs of alternative energies reduced, the Paris Agreement signed and ratified, now, she says, the fossil fuels sector is striking back.
She says they do it by spreading fake news, creating myths about restrictions on cars, speed limits, blackouts, globally, but especially in the USA under the Trump administration. So, she argues, we have to defend the energy transformation. The window of opportunity for climate action is still open, but we are losing time.
The power of fake news
Kemfert’s aim is to debunk the myths, which she is convinced are being used to give renewable energy a bad image. Some of the examples she cited to me are false claims that renewables are more expensive, or that reliance on alternative energies will mean blackouts.
“This has never happened in Germany”, she notes, the country that gave the “Energiewende” its name and pressed ahead with the transition to renewables in recent years.
So how can fake news of this kind make such an impact that Kemfert and other like-minded experts are worried about an oil and coal revival?
“If you repeat this all the time, and repeat it on social media, people think it’s true”, she told me.
“The danger is that they can be successful”.
“The global energy transition is in danger”, she is convinced. “We are losing time to bring greenhouse gases down and help the planet to survive.
“The lobby of the fossil empire is extremely strong… the whole campaign with myths and fake news is really successful, because a lot of people believe what they say”.
So are the fossil fuel lobbyists just better at getting a message across than the other side? There could be something to that, Kemfert agreed. She says the “green lobby” is not aggressive enough. People think “we are the good ones, the energy transition comes by itself”- this is not true. Now it’s time to fight for it”.
Time to march?
She calls on all scientists and people who want to protect free and democratic science, to take part in the Marches for Science, planned to take place round the globe on April 22nd.
Of course I wanted to know how she thought the global counter-attack by the “fossil empire” would impact the Arctic.
Yes, she said, this push for a fossil fuels revival could provide additional motivation to those who would like to push ahead with Arctic drilling, as climate change makes for easier and less expensive access:
“There are some aggressive industries, especially coming from the oil and gas sector, who have interest to drill for oil in the Arctic region.
For them, she says, easier access thanks to climate change would be “a nice, so-to-say side effect”.
But for the planet as a whole, climate change is so dangerous that any potential short-time business benefits are just not worth thinking about, says Claudia Kemfert:
“As a climate economist, I cannot say this (oil from the Arctic) makes economic sense, because the costs of climate change are much higher than lower costs, for example, for drilling oil in the Arctic. The costs of global climate change are so high that it cannot outweigh the cost reduction of oil drilling in the Arctic when there’s low ice. We have to move away from oil and gas, this is why it’s more economically efficient to go for an energy transition instead of drilling in areas where we have climate impacts, we are causing environmental difficulties and where we know that burning these fossil fuels will create climate change. That’s really the wrong way to go”.
Kemfert’s book is only being published in German at the moment, but there is more info on her home page, and a longer version of the English interview I conducted with her will be coming up soon on Living Planet and on the DW website.

Arctic sea ice: is the minimum maximum the new normal?
If you blinked, you might have missed it. The confirmation came this week that the Arctic sea ice reached yet another all-time low this past winter. It came and went, without too much ado.
Maybe the excitement was just past. The maximum extent was actually reached on March 7th, but of course you can only be sure it is really not going to spread any further once it has definitely been retreating for some time with the onset of spring.
I was waiting for the NSIDC confirmation, but not with any doubt in my mind that it would tell us officially the maximum for this season would be a minimum.
The danger is a “so what?” kind of reaction, or resignation, with the feeling that nothing short of some kind of unprecedented experimental geo-engineering could save the Arctic summer sea ice in the coming years, as the world continues to warm.
Lowest on record
The National Snow and Ice Data Center (NSIDC), part of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder, and NASA confirmed this week that Arctic sea ice was at a record low maximum extent for the third straight year.
It reached the maximum on March 7, at 14.42 million square kilometers (5.57 milion square miles). Since then, it has started its annual decline with the start of the melt season. Some time in September it will reach its minimum.
This year’s maximum is the lowest in the 38-year satellite record. NSIDC scientists said a very warm autumn and winter had contributed to the record low maximum. Air temperatures were 2.5 degrees Celsius (4.5 degrees Fahrenheit) above average over the Arctic Ocean. Against the background of overall warmth came a series of “extreme winter heat waves over the Arctic Ocean, continuing the pattern also seen in the winter of 2015”, NISDC said in a statement.
The air over the Chukchi Sea northwest of Alaska and the Barents Sea north of Scandinavia was even warmer, averaging around 9 degrees Fahrenheit (five degrees C) above the norm.
NSIDC director Mark Serreze said in his statement: “I have been looking at Arctic weather patterns for 35 years and have never seen anything close to what we’ve experienced these past two winters.”
The winter ice cover was also slightly thinner than that of the past four years, according to data from the European Space Agency’s CryoSat-2 satellite. Data from the University of Washington’s Pan-Arctic Ice Ocean Modeling and Assimiliation System also showed that the ice volume was unusually low for this time of year.
Record summer melt ahead?
“Thin ice and beset by warm weather – not a good way to begin the melt season,”, said NSIDC lead scientist Ted Scambos.
A low maximum does not necessarily mean the minimum to be measured in September will also be a record low, as it depends on summer weather patterns. But Julienne Stroeve from NSIDC and professor of polar observation and modeling at the University College London said “Such thin ice going into the melt season sets us up for the possibility of record low sea ice conditions this September”.
“While the Arctic maximum is not as important as the seasonal minimum, the long-term decline is a clear indicator of climate change”, said Walt Meier, a scientist at the NASA Goddard Space Flight Center Cryospheric Sciences Laboratory and an affiliate scientist at NSIDC. Iceblog readers might wonder if that is stating the obvious, but given the attitudes of the US administration, you can’t take anything for granted.
The September sea ice measurements began to attract attention in 2005, when the ice extent first shrank to a record low over the period of satellite observations. It broke the record again in 2007 and in 2012. There used to be little interest in the maximum extent of the Arctic sea ice at the end of winter. I can remember reading with concern and writing a piece about the maximum extent also reaching a record low in 2015.
“Arctic sea ice extents have followed a steady downward trajectory since the start of the 21st century – at the same time global temperatures have reached new record highs. Betides setting multiple record low summertime minimum extents, Arctic sea ice began to exhibit a pattern of poor winter recovery starting around 2004.”
Living on thin ice
I remember an expedition to Alaska in 2008, when locals at Barrow told me about their personal experiences of the sea ice becoming thinner and less dependable. Some years later I heard similar reports from people in Greenland, who were selling their sled dogs and buying boats in preparation for changing from ice to open water fishing. The data backs them up.
Yereth Rosen, writing for Alaska Dispatch News, draws attention to the problems of continuing to collect that data. She quotes NSIDC’s Serreze:
“Just how well the center will be able to track sea ice in the future remains unclear. No new satellite is expected to be in place until 2020, and there are concerns about potential interruptions in the record that goes back to 1979… We’re at a situation where the remaining passive microwave instruments up there are kind of elderly. If we have satellite failures, we could lose that eye in the sky”.
Now there is a worrying thought.
Against the background of budget cuts proposed by the Trump administration, that – to put it mildly – does not regard tracking climate change as a high priority – scientists are understandably worried about the future of scientific research on climate and environment related issues.
Method in the madness?
Without reliable continuous satellite data, it would be much harder to track how climate change is affecting the polar regions, the ocean and our planet in general. This may well be the intention of climate-change deniers behind the scenes. But climate change itself will not go away – and the impacts will be increasingly evident.
Tim Ellis, writing for Alaska Public media, quotes Serreze as saying the polar ice cap will not last long if the region continues to warm at this rate.
“We are on course sometime in the next few decades, maybe even earlier, to have summers in the Arctic where, you go up there at the end of August, say, and there’s no ice at all.”
“The view from space in the fall of around 2040” , he went on – assuming we still have satellites to take the pictures – “will be of a blue Arctic Ocean, aside from some scattered icebergs and clusters of pack ice”.
I don’t know about you, but I find that a rather depressing thought.
Implications for the rest of the globe
Andrea Thompson, for Climate Central, writes “even in the context of the decades of greenhouse gas-driven warming, and subsequent ice loss in the Arctic, this winter’s weather stood out.”
She also reminds us of the global impacts of a warming Arctic and decline in sea ice:
“The Arctic was one of the clear global hotspots that helped drive global temperatures to the second- hottest February on record and the third-hottest January, despite the demise of a global heat-boosting El Nino last summer.”
This week the UN’s World Meteorological Organisation (WMO) said 2016 had been the hottest year ever recorded, and that the record-breaking heat had continued into 2017, sending the world into “truly uncharted territory”.
“The dramatic melting of Arctic ice is already driving extreme weather that affects hundreds of millions of people across North America, Europe and Asia, according to emerging research”, Damian Carrington writes in the Guardian.
On March 15th, Carrington published an article entitled “Airpocalypse smog events linked to global warming”, referring to extreme smog occurrences in China.
Optimism – the only way to go?
This week I interviewed German oceanologist and climatologist Mojib Latif. I wanted to find out whether the highly unusual extreme rainfall and flooding happening in Peru could be explained by natural cycles or was likely to be a climate change impact which could reoccur. You can read the interview here or listen to it on my Living Planet show this week online or on soundcloud.
The professor stressed that the scientists are baffled, because it is not really the time for an el Nino, although this seems to be a “coastal el Nino”, driven by exceptionally warm water off the coast. Of course he is reluctant to attribute any single event to climate change. He stated unequivocally, though, that the warming of the ocean worldwide was absolutely inexplicable without anthropogenic CO2 emissions, that this is all in line with climate models and that we should all be preparing for an increasing number of increasingly extreme weather events, as the world warms.
He says the governments of the world (apart perhaps from the new US administration) are in no doubt that climate change is happening and they need to halt it. But they have so far failed in their attempts.
When I asked Professor Latif if he still felt optimistic, he told me we really had no other choice. While critical of the lack of government action, he is convinced the world will realize that renewables are ultimately far superior to fossil fuels and will ultimately prevail. The question is whether that will happen in time. As far as the Arctic summer sea ice is concerned, I have to go with a Scots expression: “A hae ma doots”.

Arctic Council: business as usual with USA under Trump?
As the USA comes to the end of its two-year Chairmanship of the Arctic Council, the organization’s “Senior Arctic Officials” met in Juneau, Alaska, last week to prepare for a final ministerial meeting in Fairbanks in May 11th, before Finland takes over the chair. US Ambassador David Balton is currently Chair of the SAO. At a press briefing in Juneau on Friday, it comes as no surprise that one of the questions that interested journalists most was how US Arctic policy might change under the Trump administration and whether that was already happening.
Climate skeptics at the helm?
Given that the Arctic is one of the regions of the globe being affected most rapidly and dramatically by climate change, it does not seem unrealistic to imagine that the climate skeptical views of President Trump and some of his key advisors will have more than just a little impact on the high north.
President Trump’s environment chief Scott Pruitt recently hit the headlines when he again denied that global warming is caused by fossil fuel emissions. The incoming head of the key Environmental Protection Agency (EPA) told the American television channel CNBC he “would not agree” that carbon dioxide from human activity was the primary cause of global warming.
When Pruitt was attorney general in Oklahoma, he helped sue the EPA 14 times. He told CNBC that “tremendous disagreement” remained over human impact on the climate and said the Paris accord amounted to a “bad deal.”
When the foreign ministers of the eight Arctic Council states get together in May, it is US Secretary of State Rex Tillerson, former CEO of the energy giant EXXON, who should be the man in the chair. One of the three priorities of the US chairmanship has been climate change. An interesting combination. So will the ex fossil fuels chief be there?
“We have recommended to Secretary Tillerson that he attend the Arctic Council Ministerial. He is the Chair of the Council. We don’t have a decision yet, as Secretaries of State are busy people. But the last three times the Arctic Council met at the ministerial level, a US secretary of state attended. So it’s my hope that he will come. Certainly the government and people of Alaska would like him to be here.”
Continuity or change of direction?
Drastic budget cuts affecting climate and environment and changes in personnel at the State Department and elsewhere in the administration were also on the agenda at the Juneau briefing (which was joined online by journalists around the world). So how is this affecting the work of the Arctic Council?
“So far I see no direct effect on participation in the Arctic Council either in the lead-up to our own ministerial or beyond, but the picture is not entirely clear yet,” said Balton.
“So far”, and “not yet” seem to be key words.
When it comes to whether and if so how US participation in the Arctic Council and US goals and priorities relating to the Council and to the Arctic have changed or may change under the Trump administration, Balton expressed optimism about continuity:
“I have been working on Arctic issues for the US government for the best part of 20 years. And what I can say is that US interests in the Arctic and our goals and objectives for the Arctic have not changed appreciably over time. There was a first statement of US Arctic policy issued during the Presidency of Bill Clinton. It laid out 6 basic goals of our nation in the Arctic. When George W. Bush became our President, they reiterated those very same goals, in the context of another Arctic policy statement that was put out. And when Barack Obama became President there was a question of whether the Bush administration policy would stand. And it did. It was reaffirmed during the Obama administration. And we built on top of the policy something known as the national strategy for the Arctic region. What all these documents have in common is more important than what separates them.”
Balton did accept that there had been changes of emphasis, but not in the fundamental view.
“The real interests of the United States in the Arctic have very much to do with the state of Alaska and its needs and interests, and keeping the Arctic a peaceful stable place is certainly a non-partisan issue in the United States.”
America first in the Arctic?
Presumably, as long as this fits with President Trump’s “America first” policy, all will be well. The question is how that plays out when other major Arctic players put the interests of their own countries first.
“One Arctic” was the overall theme of the US Chairmanship over the last two years. But when it comes to reconciling the geopolitical not to mention economic interests of Arctic states, cooperation might just become a little more tricky.
In September 2016, the International Security Advisory Board (ISAB), a Federal Advisory Committee established to provide the Department of State with a “continuing source of independent insight, advice, and innovation on scientific, military, diplomatic, political, and public diplomacy aspects of arms control, disarmament, international security, and nonproliferation” published a “Report on Arctic Policy” in response to a request to “undertake a study of Russia’s interests, intentions, and capabilities as it has been increasing its presence – both military and civilian – in the Arctic.”
Interesting times ahead.
The wind of change?
So far, the new administration has not turned its attention to the Arctic in particular, Balton told the journalists:
“There have been signals about climate change policy, but even those are not – at least not to me – clear yet. We do know that the Finns intend to highlight the Paris Agreement as part of their chairmanship program, but they have many other aspects they hope to highlight as well, including the sustainable development goals that the United Nations has announced.”
It remains to be seen whether the Trump administration will keep to the Paris Agreement or not. And when it comes to sustainable development in the Arctic, clearly changes in the climate will play a key role.
Between now and the end of the US Chairmanship of the Arctic Council in May, it looks as if Balton and his team will be able to carry on with “business as usual”.
“So the US Arctic Council Programme was developed in the last administration, and is just coming to fruition now. Of course we are in touch with the new administration, which I’m a member of, and for the most part now our guidance is to keep doing what we’re doing. That could change between now and May, but I don’t actually expect it will.”
The question will be what happens after that.
The Arctic Council has committed to developing a long-term strategic plan. “One of the things I felt strongly about when the US took over was that we needed to get the Council as a whole to be thinking in more than two-year increments”, Balton said. “Many of the issues concerning the Arctic are longer term. And the Council must find a way to think in longer-term. So that will happen. I expect two years from now we will be finalizing the long-term strategic plan for delivery to ministers in 2019, and probably look ahead at least ten years. “
So what effect will the change of US administration have on that? Some of the journalists listening to the briefing seemed skeptical about the idea that nothing appears to have changed, although the new new administration has hugely different policies. Again, this could well be just a matter of time:
“I think it’s fair to say that there has been no fundamental change in the way that the US is participating in the AC yet. This administration like past administrations may wish to put its own stamp on US Arctic policy. That may occur at some point. But it has not happened yet.”
Monitoring a rapidly changing Arctic
In response to a question about ocean acidification, the US ambassador described the increase in ocean acidification by 30% worldwide as “staggering” and said it was quite clearly caused by CO2 emissions.
There are not enough platforms in the Arctic to monitor this fully, he said, describing it as “one of our ambitions” to change that.
That brings us back to the crucial role played by US bodies, especially the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA) in monitoring the planet.
Today, more than thirty leading Florida scientists published an open letter to President Trump, coming out strongly against White House’s proposed cuts to the earth sciences programs at NASA and NOAA. They call on the President to recognize climate change and resulting sea level rise, which is, of course, of existential importance to Florida in particular.
Concern is mounting in the scientific community that the new administration will try to silence efforts to educate the public on climate change.
Christina DeConcini, Director of Government Affairs at the World Resources Institute, whom I interviewed recently about the Trump administration’s climate and environment policies, said in a statement on today’s letter:
“The proposed budget cuts are an affront to the integrity of science and a large body of crucial work on the impacts of climate change that increasingly damage the United States. As the most vulnerable U.S. state to sea level rise, Floridians know this very well; it persistently threatens their infrastructure, communities and homes.
“Research from NOAA and NASA is foundational for assessing and effectively responding to disruptive flooding and costly extreme weather damages.”
In the letter, the scientists write:
“American scientists have historically been at the forefront of scientific discoveries and innovation. America should invest heavily in our effort to understand our homeplanet and be aware of how physical changes will impact industry and society.”
They make a powerful plea for continuing support for NOAA and NASA:
“NASA and NOAA Earth science programs monitor and understand changes in our water resources and our soil. They track the conditions that affect the food and medicines we get from the oceans. These conditions impact agriculture, our military, businesses, and major industries. It is imperative to support programs that explore our planet – at NOAA and NASA and across the government. The work of NOAA and NASA is vital to life on Earth and must be continued”, the scientists write.
“NASA and NOAA’s work capture the history and the present state of the oceans, land, fresh water bodies, and atmosphere. They make it possible for us to observe changes to the planet we live on, from the vantage point of space.
For example, NASA satellites are responsible for providing the first global measurements of aerosols in our atmosphere and for understanding ozone. NASA satellites from the GRACE and ICES missions discovered unexpected rapid changes in Earth’s great ice sheets (…)”
So there we have it. Ultimately, the work of the Arctic Council cannot be separated from the issue of climate change and scientific monitoring.
Perhaps it was fortunate that the US Presidency of the Arctic Council coincided with the Obama period in office, where some decisions were taken in the interests of the region.
It will be up to Finland to direct operations for the next two years, from May onwards. But, clearly, regardless of what happens in the Arctic Council, the overall policy of the new US administration will have a key impact on what happens in the Arctic.
The latest SWIPA, (Snow, Water, Ice and Permafrost in the Arctic) report on the cryosphere will be presented to the ministerial gathering in May. It is unlikely to make happy reading. Climate change will have to be a major factor. And given the Trump administration’s policies so far on that issue, the work of the Arctic Council will not be able to carry on regardless.
